Chapter 2, Problem 7PP
It is difficult to make a budget that spans several years, because prices are not stable. If your company needs 200 pencils per year, you cannot simply use this year’s price as the cost of pencils 2 years from now. Because of inflation the cost is likely to be higher than it is today. Write a

In various applications, you are often asked
to compute the mean and standard
deviation of data. The mean is simply the
average of the numbers. The standard
deviation is a statistic that tells you how
tightly all the various data are clustered
around the mean in a set of data. For
example, what is the average age of the
students in a class? How close are the ages?
If all the students are the same age, the
deviation is 0.
Write a program that prompts the user to
enter any number of values into a double
array, and then calculates and displays the
mean and standard deviations of these
numbers using the following formulas:

- Imagine you are working for a lumber company, and your employer would like a program that calculates the cost of lumber for a customer order. The company sells pine, fir, cedar, maple, and oak lumber. The lumber is priced by board feet. One board foot equals one square foot that is one inch thick. The price per board foot is given in the following table: Pine 0.89 Fir 1.09 Cedar 2.26 Maple 4.50 Oak 3.10 The lumber is sold in different dimensions (specified in inches of width and height, and feet of length) that need to be converted to board feet. For example, a 2 x 4 x 8 piece is 2 inches wide, 4 inches high, and 8 feet long, and is equivalent to 5.333 board feet (2 * 4 * 8 = 64, which when divided by 12 = 5.333 board feet). Create a blank c++ Give the customer instructions and then ask the user (customer) to identify the items they wish to purchase by inputting the type of wood, the length, width, & heights of the board, and the number of boards they desire.

- Write a program that will read an executive's job number, level number, and basic pay and then compute the net salary after withholding income tax. Problem analysis: Gross salary = basic pay + house rent allowance + perks Net salary = Gross salary - income tax. The computation of perks depends on the level, while the income tax depends on the gross salary. The major steps are: 1. Read data. 2. Decide level number and calculate perks. 3. Calculate gross salary. 4. Calculate income tax. 5. Compute net salary. 6. Print the results. Program: A program and the results of the test data are given in statement should be an executable statement. That is, the label stop: cannot be the last line. Fig. 5.15.

For simplicity, suppose that the oil sits on top of the water in the form of a circle. Write a program that prompts the user to enter the rate at which the ruptured pipe pumps oil (in gallons) per minute, the thickness of the oil on top of the water, and the number of days for which the area is covered by the spilled oil. The program outputs the spilled area (in kilometer) and the volume of oil (in gallons) on top of the water after each day.arrow_forwardA supermarket is doing a sales promotion for soft drinks. If one day you buy soft drinks and bring the empty bottles the next day, they exchange each set of K empty bottles for a full one. A customer wants to make the most of this offer and therefore bought several bottles on the first day of the promotion. Now he wants to know how many bottles he will have at the end of the second day of the promotion if he use it to the fullest. Make a program to calculate this. Input The first input line contains integer T (1 ≤ T ≤ 10000), which indicates the number of test cases. In each of the following T lines come two integers N and K (1 ≤ K, N ≤ 10000), respectively the number of soft drinks bought and the number of empty bottles to gain a full. Output For each test case print the number of bottles that the customer will have on the second day, if he makes the most of the offer.arrow_forward

For example, a beginning teacher in the Lexington School District might be paid $30,000 the first year. For each year of experience after this first year, up to 10 years, the teacher receives a 2% increase over the preceding value. Write a program that displays a salary schedule, in tabular format, for teachers in a school district. The inputs are: 1. Starting salary 2. Annual percentage increase 3. Number of years for which to print the schedule Each row in the schedule should contain the year number and the salary for that year An example of the program input and output is shown below: Enter the starting salary: $30000 Enter the annual % increase: 2 Enter the number of years: 10 Year Salary 1 30000.00 2 30600.00 3 31212.00 4 31836.24 5 32472.96 6 33122.42 7 33784.87 8…arrow_forwardYou found an exciting summer job for five weeks. It pays a per hour rate (which will be input to the program), and you will work the same number of hours each week (also input). Suppose that the total tax you pay on your summer job income is 14%. After paying the taxes, you spend 10% of your net (after tax) income to buy new clothes, accessories, and school supplies. After subtracting those items from your budget, you use 25% of the remaining money buy savings bonds. In addition, your parents buy additional savings bonds for you at 50% of the amount that you buy. Write a program that prompts the user to enter the pay rate per hour and the number of hours you will work each week. The program then outputs the following:• Your income before and after taxes for your summer job.• The money you spend on clothes, accessories, and supplies.• The money you spend to buy savings bonds.• The money your parents spend to buy additional savings bonds for you.Your input for this program should be only…arrow_forward
- Given a certain temperature in Fahrenheit and a maximum wind velocity (speed) in Miles Per Hour, calculate and display a series of wind chill factors from a wind velocity of 1 MPH to the maximum wind velocity in a table. The user is allowed to specify a maximum wind velocity of up to 50 MPH.Here are the programming instructions for this project: •You must use coding techniques from only Chapter 1 through Section 5.1 in our textbook. You may not use any other coding techniques from any other sources. • Create a project and class in BlueJ named Project2 • In main(), do the following: -Prompt the user to enter the current temperature and use a Scanner object to store it in a double variable.oCall a method named getVelocity that returns an integer and has a Scanner parameter. This method must use a either a while loop or a do-while loop to prompt the user to enter the maximum wind velocity (speed) and return it. A valid value for the maximum wind velocity is between 2 and 50…arrow_forwardWhen analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. For this program, adjust the values by subtracting the smallest value from all the values. The input begins with an integer indicating the number of integers that follow. Ex: If the input is: 5 30 50 10 70 65 the output is: 20 40 0 60 55 The 5 indicates that there are five values in the list, namely 30, 50, 10, 70, and 65. 10 is the smallest value in the list, so is subtracted from each value in the list. For coding simplicity, follow every output value by a space, including the last one. 272772.1571588arrow_forwardA teacher at Leva Primary School needs to divide her class in different group sizes according to the activity they have to do. This will help her to prepare workstations for each group. For example, for art projects the class has to be divided in groups of 6; for science projects the class has to be divided in groups of 4. She asked you to write a program to determine the number of groups as well as the number of pupils who are left to form a smaller group. There are 56 pupils in the class.The program has the following structure:• Declare three int variables nrPupils, nrGroups, and nrLeft. nrPupils represents the number of pupils in a class, nrGroups represents the number of groups the class is divided into, and nrLeft represents the number of pupils, if any, who are in the remaining smaller group.• Assign the value 56 to nrPupils.• Declare an int variable groupSize that is used by a cin statement to input a value from the keyboard and store the size of the groups the teacher…arrow_forward
